October 2023 G&G Blog

Welcome back to the 2023-2024 season. We hope everyone enjoyed their summer. We look forward to getting the course open for play and seeing everyone back at the club.

This past summer was a very hot and dry summer. We received 0.4 inches of rain from this year’s monsoon season versus 13 inches from the prior monsoon season. The greens did very well this summer with the drier conditions. However, the hot and dry weather presented some challenges to the water budget. We had a very good transition this past summer and did not need excess water for the Bermuda grass to recover. Through all the challenges we were able to maintain our water budget through the summer and expect to meet our annual allotment.

The lack of monsoon storms also provided a chance to catch up and work ahead on the desert maintenance leading up to overseed. We spent a good portion of August and September blowing and cleaning, raking debris, and removing random sprout plants from all of the deserts. We have started over on the deserts now trimming all plants however we did not finish all the trimming of the deserts. Holes 10-17, and 3-7 will continue trimming and cleaning over the next several weeks as the course opens.

As you may have noticed our overseed schedule changed this year. This year our closure for overseeding was 5 weeks in total. Fall greens aerification was pushed back 2 weeks and was combined with overseeding to create an extended period compared to the prior years. This was done for several reasons. The first reason was to aerate the greens in more favorable weather conditions for the health of the greens. Second, it removed the need for golfers to have to play on sandy aerified greens for 2 weeks leading up to overseed. Third, the G&G Department was able to make all necessary herbicide applications away from all play. Fourth it provided a built time for the restoration of the collars this year and for the future when the collars will have to be re-sodded to combat the Bermuda encroachment. Fifth it pushed back overseed 1 week and allowed the ryegrass to be grown in a slightly cooler period to establish with less pressure from the existing Bermuda grass.  Our overall goal was to make one inclusive period to perform all necessary practices while removing any disruptions to the course that would affect play prior to overseeding and creating much healthier conditions for the golf course.

During the week of September 25th, the greens were verticut and ariefied with ½ tines and top-dressed with 75 tons of sand. In addition, the outside 24” of the bentgrass collars were cut and dug out approximately 2-3” to remove all Bermuda encroachment. Approximately 50 tons of USGA green mix was backfilled and packed band in this area around every green. 14,000 sq feet of bentgrass sod was contract grown 10 months ago in northern California. 2 deliveries of sod were brought in on refrigerated trucks to re-sod the collars. This was a very large and labor-intensive practice, but a very necessary practice to protect Bermuda grass from encroaching into the interior of the greens. This practice can be expected to occur every 2-3 years pending weather conditions.

Overseed went very well this year. The weather conditions could not have been more perfect. The overseed was performed the same as it has been over the past 2 seasons. G&G used approximately 36,000 lbs. of perennial ryegrass seed to overseed this year. Very similar to what our overseeds have been for the past years.

G&G continues to clean and prepare the course of opening. An extensive amount of time has been spent in the bunkers checking depths and re-distributing the sand as needed. We have been cleaning more deserts, cleaning and polishing rakes, coolers, sand/seedboxes, trash cans, and tee markers. Multiple flower beds and pots have been added to the clubhouse area this year. We hope everyone will enjoy the added color.

The renovations to the G&G Department Building are moving forward but unfortunately at a very slow pace. All designs and plans have been submitted to the City of Scottsdale and are still pending review and permit. Several hurdles have been cleared but we are still waiting on the city to move forward. There are 3 contractors ready and waiting to finish competitive bids on the project pending the final permitted plans. Preliminary bids were received based on the non-permitted plans for budgetary purposes. Bids will be revised based on the city comments and stamped plans. There is no definitive timeline, but we are still hoping for the demo and construction to begin before the end of the year.

One large change that will be noticed at G&G will be the NW corner of the yard near the bathroom on #7 has been moved out and the 2 existing gates were combined into 1 gate to connect the east yard to the west yard. This will give some additional space to park equipment and cars and for the new portion of the building.

Another large change that will be noticed is the removal of the large oleanders along the golf course maintenance road / Cart Path 7→8. The oleanders were removed to open up the wash entrance for stormwater that comes down the #8 cart path. The oleanders were grown over the area where the water was supposed to run forcing the water to stay on the road and pushing the water into the golf course maintenance yard. It was decided to remove the oleanders to help direct the water away from the golf course maintenance building and protect the upcoming renovations to the building. Future replantings are being considered once the grading work has been completed.

We look forward to seeing everyone back at the club and look forward to providing an excellent experience for all members and guests. WELCOME BACK!!!!!

PPCC G&G Blog 

We hope everyone is enjoying their summer. If you’re still in AZ, we know you haven’t enjoyed the last several weeks. After a very mild June, we are seeing record heat for July in addition to higher humidity and dew points.  The combination of those factors has made for an unpleasant July so far.

The transition is going well. The mild June helped some of the ryegrass hang around a bit longer than we wanted but the record heat in July has now removed the remainder. A few high-traffic areas in the fairways and green surrounds have not transitioned quite as well as we would have liked but we are confident we will get these areas to grow back in soon.

We spent a good portion of June focusing on installing the existing fans, and new conduit and electrical wire for the new fans on 4,5,6,10,11 and 12. We trenched and installed about 1 mile of conduit and about 3 miles of electrical wire to power the new fans. Currently holes 10,11, and 12 are fully installed and functioning. Holes 4,5 and 6 have the fan footers, the conduit, and electrical wiring installed. Unfortunately, we are still waiting on 2 permits from the city of Scottsdale and work by APS to be able to connect to the power source. The power is coming from the north side of Pinnacle Peak Road and N. 82 Street. APS needs to increase the size of the wire and install a junction box that is currently feeding Cox Cable and SW Gas next to the 5th tee box. Once the junction box is installed, we will run a new conduit under the oleanders and connect our newly placed break box a few feet away from the white tee on #5. As soon as the power is connected, we will place the fans on the footers that have been installed and we will be ready to run.

As is the case every year, you will continue to experience the greens slowing down, becoming softer, and ball marks become more prevalent, and much slower to recover as the summer stress continues. The high air temps, high soil temps, humidity, and high dew points are very hard on the bentgrass. Bentgrass is a cool-season grass that can survive the summer but is not very well suited for the months of July, August, and September. For example, the ideal soil temps for bentgrass is 50-65 degrees. At this point, we have not seen those soil temps since early June and will likely not see them until late September or early October. Currently, we see soil temps 70-80 degrees overnight and 90+ during the day. These high soil temps along with oppressive humidity and high air temps will significantly shrink the root depth and density and will thin the density of the leaf blades on the surface. Much of the damage is already occurring and is a naturally occurring challenge. The fans are utilized to artificially dry the air and humidity of the greens giving some relief to the greens. However, the fans cannot overcome all the stressful conditions. To aid in the process we will continue to raise the height of the cut, and change out the rollers and bed knives on our mowers to lessen the aggressiveness of the mowers. We will also do a light top dress to help firm up and protect the greens. You will continue to see staff syringe the greens with hoses to cool them and/or light 1–2-minute watering with the irrigation if we cannot keep up with hoses.

You will continue to see a white ring around the perimeter of the collars. This is by design. We spray a growth regulator that is designed to only target Bermuda grass around the greens to slow the Bermuda grass from encroaching in the green. However, it will slow the Bermuda but over time the Bermuda will advance further into the collar closer to the putting surface. The collars are scheduled to be resodded in the last week of September. We will be replacing the outer 24” of the collar to remove the encroachment. This will continue to be a repetitive practice every few years in order to keep the Bermuda grass from reaching the putting green.

The drainage project behind #8 Green has been completed. We installed a 4-foot-wide cement channel at the low point of the turf to allow for all the water to completely pass in a large rain event. This will eliminate the need to pump the water that gets dammed up in the cement basin. Additionally, we re-graded and narrowed the sides of the channel in the grass to help slow the water down as it enters the golf course.

The desert to the left of the 16th was also re-graded in coordination with the homeowners to help alleviate some significant erosion and storm damage concerns. The area was graded to help slow and turn the water so that water could pass through in a more controlled manner limiting the damage.

G&G recently completed our summer cultural practices. We aerified all areas in the fairways, tees, approaches, green surrounds, and roughs. We verti-cut and dethatched all fairways, tees, and approaches. We also did some light topdressing in the fairways and approaches. These cultural practices are very important to the health of the Bermuda grass and preparing the course for overseeding in the fall. The course is still recovering; however, the record heat is not helping. Even Bermuda grass doesn’t like this heat. We anticipate the course to be fully recovered in about 2 weeks.

A few small projects have begun for the renovation of the G&G Building. Since we will have to operate out of our existing area while the renovation is being carried out there are a few projects to complete before the main renovation begins. We are currently partitioning 2 storerooms into smaller rooms to better utilize the space and prepare for the main renovation of the building. One large storage area is being partitioned into 3 rooms. Upon completion, we will move our pesticide storage, irrigation storage, and utility storage into the newly partitioned area. In addition, a large room next to the mechanic's garage was divided in half in order to move all the mechanic's parts inventory into a climate-controlled room. The existing part room is too small and is not climate-controlled and needs to be relocated for the renovation of the main building. Also, the 2 rear gates are being removed and the wall is repositioned further to the northwest so that there will be only 1 gate near the #7 bathroom and will also connect the east side of the yard to the west side. These small projects are expected to be completed by mid-august.

The final detailed blueprints are almost complete and are expected to be submitted to the city of Scottsdale the week of July 24th and distributed to several contractors interested in the work for finalized numbers. Original costs were estimated from a set floor plan and estimated price per square foot. If all goes according to plan the renovation of the main building is expected to start in November and hopefully be completed by late spring. The timing of the building renovations in the winter is due to a few reasons. The first is to accommodate the staff with nicer weather due to having to take lunch outside. Also, we wanted to wait till after overseed due to the need to relocate the central irrigation control computer to a mobile mini office. In the event there were difficulties with the relocation we did not want to interfere with overseeding or damage the golf course in the hotter summer weather.

We hope everyone enjoys the remainder of their summer. We look forward to seeing everyone back in the fall.
